Fire Pump Controllers  1-1 
Features 
Typical Specifications 
 
1. Approvals 
A.  The Fire Pump Controller shall meet the require-
ments of the latest edition of NFPA 20 and shall be 
listed by [Underwriters Laboratories (UL)]and ap-
proved by [Factory Mutual Research (FM)] [Cana-
dian Standards Association (CSA)] [New York De-
partment of Buildings (NYSB)] and carry the CE 
marking for fire pump service. 
2. Starting Type 
A.  The controller shall be of the combined manual and 
automatic type designed for [Full Voltage Starting] 
[Part Winding Starting] [Primary Resistor Starting] 
[Autotransformer Starting] [Wye-Delta (Star-Delta) 
Open Transition Starting] [Wye-Delta (Star-Delta) 
Closed Transition Starting] [Solid State Soft Start 
Starting] 
3. Ratings 
A.  The Controller shall have a withstand rating of 
100,000 RMS symmetrical amperes @ [208V] [240V] 
[380V] [400V] [415V] [480V] [25,000 @ 600VAC].  
4. Construction 
A.  The controller shall include a motor rated combina-
tion isolating switch and circuit breaker, mechanically 
interlocked and operated with a single externally 
mounted handle. 
B.  The isolating switch shall be rated to disconnect the 
motor load. 
C.  The isolating switch/circuit breaker combination shall 
be mechanically interlocked such that the enclosure 
door cannot be opened when the handle is in the on 
position except by a tool operated defeater mechan-
ism. 
D. The controller manufacturer shall manufacture the  
contactor, isolating switch, circuit breaker, pushbut-
tons, and enclosures.  Brand-labeled components 
will not be accepted. 
5.  Enclosure 
A.  The controller shall be housed in a NEMA Type 2 
(IEC IP11) drip-proof, powder baked finish, frees-
tanding enclosure. 
B. Optional Enclosures: 
1.  NEMA 3R (IEC IP14) rain-tight enclosure. 
2.  NEMA 4 (IEC IP66) watertight enclosure. 
3.  NEMA 4X (IEC IP66) watertight 304 stainless 
steel enclosure. 
4.  NEMA 4X (IEC IP66) watertight 316 stainless 
steel enclosure. 
5.  NEMA 4X (IEC IP66) watertight corrosion resis-
tant enclosure. 
6.  NEMA 12 (IEC IP52) dust-tight enclosure.
